| Abstract: | A distributed real-time database management system applied in an integrated SCADA/EMS/DTS system is presented in this paper. The system structure of memory and some features of the system are introduced, the distributed database mechanism is specified, and then the critical techniques such as automated database replication, heartbeat broadcasting and the leader election protocol are described. The system based on the principle of this paper has been put into practice, and used in some power system control centers in China. |
